  • We report the discovery of molecular gas streams orbiting around an invisible massive object in the central region of our Galaxy, based on the high-resolution molecular line observations with the Atacama Large Millimeter/submillimeter Array (ALMA). The morphology and kinematics of these streams can be reproduced well through two Keplerian orbits around a single point mass of $(3.2 \pm 0.6)\times 10^4 \ M_\odot$. We also found ionized gas toward the inner part of the orbiting gas, indicating… CONTINUE READING
